Hey Ruf! I'm going to a wedding too next month and was having the same dilemma, but I've decided I'm going to wear a dress I already have - it is a crinkly flowy material, comes down to my calves and has a satin sash around the waist....it has a low v-neckline so I can just push one side away to feed DS. I will use my breastfeeding shawl around my shoulders to be really discreet.
